or cIIIcAeo,y ILLINOIS RAIL SILENCING TIE PLATE Application led April11, 1931. Serial No. 529,865.

My invention relates to tie plates for railroad rails, and its object isto provide a n ew and improved device of this character whlch .when usedin the ordinary manner of tie form as shown in ders, and the plate neednot be disturbed in making rail renewals or replacements.

The body of the late is made in skeleton ig. 1 to provide a cen- 5plates between the rail and ties provides a tral opening or space 15 forsuitable resilient resilient seat for the rail-base and acts as a pads16 which are seated in these spaces, as

sound-deadening or silencing device, and .in which the metal plate doesnot carry or distribute the load as is4 usuallydone by tieshown forexample in Fig. 5. The pads substantially fill these spaces, thoughslight clearance between their edges and the walls plates. Otheradvantages will be apparent v of the plate may be left if desired, andthe from the disclosure.

In the accompanying drawings, Fig. l is a top plan view showing atie-plate constructed in accordance with my invention, the associatedpad being omitted for convenience of showing the plate itself; Fig; 2 isan end that of the rail-base, and as they are thickery view of the plateof Fig. 1; Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1looking in the direction of the arrows; Fig. 4 is a detail sectionalview taken on the line 4 4 in Fig. 1, and Fig. 5 is a viewl incross-section showin the plate and its resilient pad assembled 1n placebetween a railbase and a tie.

In the drawings the reference letter A designates the base of a rail, Bits web and one of the cross-ties on which the device 1s supported.

The tie-plate body consists of a flat metallic strip 1Q provided neareach side with a flange 11 which preferably extends the full length ofthe plate and provides avshoulder for the corresponding edge of therail-base. The shoulders may be integral for their en tire length orthey may be in sections as shown, and spike-holes 12 are formed outsidethe shoulders to receive suitable spikes (not shown) to fasten theplateto the tie.

Adjacent each spike-hole the plate and its shoulders may be Vbeveled asshown at 14 to form seats for the spike-heads; in the presentexemplifcation the seats are shown as circular to accommodateroundheaded spikes.'v

The shoulders are of sucient height to extend above the edges of therail-base, and the distance between the shoulders is slightly greaterthan the Width of the rail-base. When the rail isassembled on the plateit is held in place and guided by' the shoulpads are thicker than theadjacent walls of the plate so that in their normal relation therail-base is carried by the pads without contacting with the end'pieces17 of the plates. The pads have a widt slightly greater than than theplates all wear comes on the pads; when they become worn or lose some oftheir resiliency they can be removed and renewed by merely lifting therail without disturbing the plate or tie. r The pads preferably areslightly wider than the rail-base, and are of such length that the ends17 of the plate have sucient metal to give them proper strength whenplaced under tension by the rails under traffic. The plate itselfl doesnot carry or distribute the load as ordinary tie plates do, it does notget worn or bent under the action of the rails in traffic, and does notwear the tie, as the pads carry the load through the plate openingdirectly to the ties and hold the rails out of contact with the plates,and are in turn held in proper position under the rails by the walls ofthe openings l5. These tie plates when placed on the ties, whether plainor creosoted, will outlast the ties. The

` rail may be fastened to the plate by any suitable means. The padsrotect the tie from the Wear which is causedj y plates upon which therails rest, thus prolonging the life of the ties and obviating thenecesslty of their frequent replacement.

I claim:

1. A metallic rail plate having a body provided with opposite shouldersand an intermediate ofpemng through its body, and a resllient pa shapedto ft into said opening.

2. `Ametalllc rail late having integral slde and end portions orming anintermediate opening, shoulders onsaid side portions forming a space forthe base of an associated rail and a resilient pad shaped to 't intosaid opening and'thicker than the walls of said opening. I

3. A metallic rail plate having a skeleton body composed of oppositesides and opposite endsenclosing an opening through the intermediteortion of the plate Wider than the ange o an associated rail, shoulderson the sides higher than said rail-flange, and a .resilienti pad shapedto it into said opening and thicker than the adjacent walls thereof andWider than said i'ail-iange.

In testimony whereof I hereto aiix my signature. WARREN M. osBoRN.
